[0024] It should be noted that: through the arrangement of the connecting assembly, the mounting rod 201 and the detection rod 202 are rotatably connected, so that the detection rod 202 is facilitated to tilt when the detection rod 202 is subjected to force interference, and the rotating ball 302 can provide gravity for the detection rod 202 to restore the vertical state when the detection rod 202 is no longer subjected to force interference with the workpiece.
[0025] Please refer to Figure 2 and Figure 3 , the identification assembly shown in the figure comprises a plurality of L-shaped plates 401 fixedly connected to the side walls of the mounting rod 201, each L-shaped plate 401 is fixedly connected with an identification tube 402 on the side close to each other, the identification tube 402 is slidably connected with an identification rod 403, one end of the identification rod 403 located inside the identification tube 402 is fixedly connected with an identification plate 404, one of the L-shaped plates 401 is provided with a distance sensor 405, the detection end of the distance sensor 405 is arranged opposite to the identification plate 404, and each identification tube 402 is provided with a telescopic assembly used for telescoping the identification rod 403;
[0026] It should be noted that: through the arrangement of the identification assembly, the interference tilt of the detection rod 202 is identified, so that the position deviation of the detection rod 202 is detected in time.
[0027] It should be noted that: the model of the distance sensor 405 is AC-M18-A50 / 100, which is convenient to purchase in the market and has a low price.
[0028] Please refer to Figure 2 and Figure 3 The telescopic assembly in the drawing includes a telescopic ring 501 connected to the identification pipe 402 in a sliding manner, the telescopic ring 501 is provided with a spring 502 near one side of the identification rod 403, the other end of the spring 502 is connected to the identification plate 404, and the identification pipe 402 is provided with an adjusting assembly for adjusting the elastic force of the spring 502.
[0029] It should be noted that: through the setting of the telescopic assembly, each identification rod 403 is used to push the side wall of the detection rod 202, and at the same time, when the detection rod 202 no longer interferes with the workpiece under force, the detection rod 202 will be pushed to restore the vertical state, thereby facilitating the next detection.
[0030] Working principle: during the machining process of the machine tool, first, the workpiece needs to be placed on the workbench, and then the workpiece is clamped by using the plurality of clamping assemblies Figure 3 After clamping the workpiece, in order to ensure the position accuracy of the workpiece, the position of the workpiece needs to be detected.
[0031] During the detection of the position of the workpiece, first, the mounting rod 201 is installed by using the tool holder, and then the detection rod 202 at one end of the mounting rod 201 is moved close to the workpiece by the tool holder through a predetermined program, when the detection rod 202 moves according to the predetermined program, and does not interfere with the workpiece, it indicates that the position of the workpiece is correct.
[0032] If the detection rod 202 moves according to the predetermined program and interferes with the workpiece, under the action of the interference resistance and the rotation of the connecting assembly, the detection rod 202 will be offset, when the detection rod 202 is offset, each identification rod 403 will move, when the distance sensor 405 detects that the identification rod 403 moves, an electrical signal will be sent to the machine tool system, so as to analyze and process by using the processor, and an alarm signal is displayed through the display screen, so as to display the detection result to the operator, so that the operator can master the detection result in time, thereby ensuring the detection accuracy of the position of the workpiece under the detection of the detection assembly, and the whole structure is simple, convenient to maintain, and the operation convenience of the workpiece position detection is improved and the cost of the workpiece position detection is reduced.
[0033] Example 2
[0034] Please refer to Figure 3The embodiment is further illustrated by the example 1. The adjusting assembly in the drawing includes two mutually symmetrical adjusting tubes 601 connected to the identification tube 402 by sliding. One end of each of the two adjusting tubes 601 is connected to the telescopic ring 501. One of the two adjusting tubes 601 is connected to the adjusting rod 602 by sliding. One end of the adjusting rod 602 is connected to the bottom wall of the identification tube 402. The other of the two adjusting tubes 601 is connected to the threaded rod 603 by screwing. One end of the threaded rod 603 away from the identification plate 404 is fixedly connected to the connecting rod. The other end of the connecting rod penetrates through the L-shaped plate 401 and is fixedly connected to the adjusting ball 604.
[0035] It should be noted that the elastic force of the spring 502 changes due to the excessive extrusion and pushing of the spring 502 during multiple detections of the detection rod 202. Therefore, the elastic force of the spring 502 with changed elasticity needs to be adjusted to ensure that the pushing of each identification rod 403 to the detection rod 202 is equal and the detection rod 202 is in a vertical and centered state.
[0036] During the adjustment of the elastic force of the spring 502, the adjusting ball 604 is rotated to drive the threaded rod 603 to rotate. Under the threaded meshing transmission of the threaded rod 603 and the adjusting tube 601 and the guiding action of the adjusting rod 602, the telescopic ring 501 is moved in the identification tube 402. During the movement of the telescopic ring 501, the identification rod 403 pushes against the side wall of the detection rod 202. When each identification rod 403 keeps synchronous with the detection rod 202 and the length of the identification rod 403 extending out of the identification tube 402 keeps consistent, the adjustment of the elastic force of the spring 502 is completed. Then, the synchronous pressing of each identification rod 403 to the detection rod 202 is kept, so that the detection rod 202 keeps vertical during long-term use, and the long-term use and accuracy of the detection assembly are improved.
[0037] Please refer to Figure 3 Each side wall of the identification rod 403 is provided with a scale line 7.
[0038] It should be noted that the scale line 7 is used to identify the extrusion and pushing force of the spring 502 to the identification tube 402, and is used to refer to the extension length of the identification rod 403 when the elastic extrusion force of the spring 502 is adjusted.
